After noticing that a large number of the playlists I come across in some manner make a request for suggestions, I realized there isn't really a straightforward way to do such a thing. That was then. Now, if you want to allow other members to suggest a video for your playlist, tick the "Allow viewers to suggest videos" box in its settings. This will present other members (only other members; you can't give yourself suggestions, silly) who are viewing the playlist a box in which a video's URL may be pasted.



These suggestions are shown only to the playlist's owner and also note the member that made the suggestion. If the owner decides to add the video, the suggestion will automatically be removed.



Give it a whirl and let us know your thoughts, requests, complaints here. One thing I'm particularly curious to know is if you think everyone should be able to see the videos that have been suggested for a playlist. Thoughts?
